I didn’t quite catch you at this point because he confirms that PRR’s are actually disabled.
And a little question for you, @aceran715-51-user . Did you reboot your device before doing the last backup?
Not yet, let me power off and on and then try again? Will upload and reply with the link within 10-ish minutes.
EDIT -
As I had already processed write.bat as per previous instructions, I did not run it again but simply turned off the laptop, waited few minutes, and turned it back on.
@aceran715-51-user And now it successfully writes. Which is to be expected. You didn’t need to confirm this by making a backup again. A simple yes or no to the question of rebooting would have been enough, but thanks anyway. @BDMaster You can continue, it was not me who modifying his bios.
@Sweet_Kitten (i love u bro, u know it) so you can continue or doing anything as i have i big respect for u and i will continue to say say yet you’re better modder i know !
Thank You so much, I am utterly thankful. It flashed great and the laptop boots fine into BIOS. However, I had a couple of questions -
1. Can I write original vars.txt -> reboot -> flash original BIOS using original driver file to compare both of them (without any damages hopefully); and then repeat with varsmod and new BIOS to come back to the MOD? 2. I have included screenshots from new BIOS @ https://imgur.com/a/V1Mx8eK for points 3 and 4 below - 3. As can be seen in the images and their description on imgur site, some crucial options are still not visible / grayed out. 4. Although advanced and power tab are unlocked (many many thanks), but I still cannot find two major options I was originally looking to tweak - namely, unlock legacy boot mode and toggle between Intel RST modes (Disabled / RST premium with optane / RST standard etc)
I hope I have described my question in detail to avoid confusion.
Ok friend, the modifies made by varsmod.txt are temporary, so if you will update the Bios (Flash a bios backup or new one) or loading the default settings, or clearing the CMOS, you will lose them … so it’s more simple than you described. The process is described so :
1. Test the Eeprom Write Protection and find the variables which make that 2. Modify the variables into NVRAM (there are many ways , H2OUVE, RU shell, EFI shell, etc) 3. Modify the Bios Backup . unlocking the Menu Tabs and EFI IFR for others settings locked into IFR (Universal IFR Dumper Donovan’s tool) 4. Write back the modified Bios
This process is replicable, so you can make again and have to unlock again the variables if you will clear the NVRAM, or flash an bios backup or original bios. Now to make the comparison between bioses files to find the differences , then you have to extract (bios file is lzma compressed and / or capsulated) the modules , they are descibed by GUIDs. You can use UEFI Extract, UEFI Tool and Andy’s Phoenix tool (the best way to compare is last one) and use an Hex Editor with comparison possibilities HxD too, or Beyond Compare.
I wrote here below the hex modifies to make at this bios so you will see them without make comparison and about the IFR it’s attached and you can find the variables you want ot show , so i will unlock them for you, after this you have to reflash the Bios Mod again :
I want to heartily thank all of you for the immense good work that you’re doing for people!!!
Many many thanks. @BDMaster this went perfectly and unlocked everything I needed but not Overclocking so far.
I have Legacy mode I have AHCI/RAID toggle I have advanced and power tabs
Also, thank you for describing the process in detail, although acer laptop is my daily driver, I will attempt modding the bios of my lenovo g580 with similar steps (that also has insyde flash)
Many thanks yet again, this is really something! Warm Regards
